This razor belonged to my Granddad. My Dad is 61 and this is the only razor he remembers by Grandad ever using. It is a Gillette and I can't find in date codes or other markings other than "Made in USA", "PAT NOS ON PACKAGE" & "REG U.S. PAT. OFF."
I started doing searches for straight razors and safety razors and found this site. After doing some looking around I dug this out and cleaned it up for use.
